Two different non-destructive techniques of characterization were coupled to study the mechanical behavior of materials inside a battery during operation: measurement of the deformation of a battery casing by strain gauge and acoustic emission due to the release of mechanical stress inside the battery materials. Experiments were conducted on a commercial Ni-Zn AA-type battery and, particularly, phenomena occurring during overcharge were considered. Beyond the example of this study on a Ni-Zn battery, these two techniques offer complementary information that can be very useful for the monitoring and management of different type of batteries.
